INTRODUCTION 

THEL  Pratt  &  Whitney  Company  invites  attention  to  the  Precision  Machinery 
illustrated    and    described   herein.      A   broad  experience,    unexcelled   facilities  and 
unfaltering  determination,  this  Company  believes,  have  solved  the  essentials  of  modern 
machinery  requirements  in  a  manner  which  will  appeal   to  the  discriminating  judgment 
of  the  Mechanical  World. 

Design  In  the  design  of  these  machines  every  known  necessary  requirement  as 
regards  stability,  power,  accuracy,  convenience  and  rapidity  of  operation  have  been 
carefully  considered.  In  their  solution  every  opportunity  for  improvement  has 
been  accepted,  many  new  features  and  refinements  having  been  incorporated  resulting 
in  the  production  of  machinery  which,  for  its  adaptation  to  the  end  sought, 
has  an  enviable  reputation  the  world  over.  Separate  departments  and  engineering 
forces  devoted  to  the  various  types  of  machines  are  maintained  at  the  Works;  thus  the 
several  lines  are  under  constant  observation  and  improvements  are  made  from  time  to 
time  to  meet  the  changing  conditions  and  to  increase  their  efficiency. 

Material  The  very  best,  so  proven  by  experience  and  careful  investigation,  is 
always  used,  regardless  of  cost. 

Workmanship  The  mechanics  employed  by  the  Pratt  &  Whitney  Company 
are  of  an  exceptionally  high  order.  The  best  devices  and  methods  known  for  the 
accurate  and  rapid  production  of  machinery  are  freely  made  use  of.  The  inspection 
system  covers  material,  detail  parts,  constant  attention  during  process  of  construction, 
as  well  as  a  most  thorough  test  of  the  finished  machine  for  alignment,  operation,  etc. 
No  work  except  of  the  highest  possible  order  is  tolerated. 

Standard  Equipments  The  tool  equipments  and  appliances  as  furnished  for 
the  various  machines  fully  cover  the  general  requirements.  The  aim  is  to  make 
these  tools  distinctive  for  their  simplicity  and  ease  of  operation  combined  with  the 
necessary  rigidity. 

Special  Equipments  For  work  out  of  the  ordinary  the  Pratt  &  Whitney 
Company  is  in  a  position,  due  to  the  separate  manufacturing  and  engineering 
departments  maintained  for  the  various  lines,  to  design  and  equip  the  machines  with 
special  tools  and  appliances  of  the  most  modern  approved  type. 

Inquiries  All  inquiries  should  be  accompanied  with  detailed  information  regarding 
the  matter  in  question,  and  where  there  is  any  doubt  full  dimensioned  blue  prints  or 
samples  should  be  furnished.  Blue  prints  and  samples  will  be  returned  when  desired. 
If  these  suggestions  are  adhered  to,  the  solution  of  the  matter  involved  is  very  often 
simplified  and  invariably  considerable  time  is  saved. 


A  list  of  branch  offices  and  agents  is  printed  on  opposite  page.  The 
representatives  in  these  offices  are  experts  and  are  kept  in  close  touch  with  the  Works 
regarding  improvements,  deliveries,  prices,  etc.,  and  are  pleased  to  be  of  service. 

Visitors      The  Works  are  always  open  to  visitors  who  are  interested  in   machinery 
manufactured  by  the  Pratt  &  Whitney  Company. 


This  catalogue  contains  in  a  concise  form  specifications  and  general

These  machines  mark  a  distinct  advance  in  Turret  Lathe  construction.  The 
introduction  of  many  new  features  and  refinements  have  made  possible  the  production 
of  a  class  of  work  which  for  accuracy  is  beyond  that  which  has  been  supposed  or 
known  to  be  obtainable  on  Turret  Lathes.  The  machines  have  an  exceptionally

Universal  Turner  with  "V"  Back-rests  Suitable  for  bar  work  and  is 
equally  effective  for  turning  toward  the  spindle  as  is  usually  the  custom  on  short  work, 
or  away  from  the  spindle  which  is  frequently  desirable  on  long,  slender  work.  Cutter 
is  made  of  high-speed  steel  and  mounted  in  a  slide  provided  with  liberal  radial  adjustment, 
which  is  governed  by  efficient  stops.  Back-rest  jaws  are  made  of  high-speed  steel  and 
can  be  easily  reversed  to  accommodate  different  diameters  by  swinging  away  the 
strap  which  takes  the  backward  thrust  of  the  jaws.  Made  for  the  i^,  2  and  3 -inch 
machines  only. 

Universal  Turner  with  Roller  Back-rests     Similar   in   construction  to 

the  universal  turner  with  "  V  "  back-rests,  with  the  exception  that  roller  back-rests  are

TAPER  TURNING  TOOL 

Suitable  for  turning  tapers  from  either  bar  stock  or  forgings.  Back-rest  jaws  may 
be  set  to  follow  or  lead  the  tool  as  occasion  may  demand.  The  cutting  tool  is  directly 
controlled  by  an  accurate  taper  bar  for  angle,  the  work  produced,  therefore,  is  of  a 
superior  order  and  is  fully  equal  to  that  obtained  from  an  engine  lathe.  The  radial 
adjustment  of  the  tool  slide  which  permits  roughing  and  finishing  cuts  is  accomplished 
through  the  taper  bar-block  screw,  accurate  adjustments  being  possible  by  means  of  the 
micrometer  dial.  In  order  to  produce  the  required  taper  it  is  only  necessary  to  plane 
a  bar  to  a  taper  one-half  of  that  required  on  the  piece  to  be  turned;  thus,  if  the  desired 
taper  is  ^  inch  to  the  foot  the  bar  should  be  planed  to  i^  inch  to  the  foot.  One 
taper  bar  planed  to  produce  tapers  ^  inch  to  the  foot  (unless  otherwise  specified)  is 
furnished  with  each  tool.  Made  for  the  i,  i^,  2  and  3 -inch  machines.

Motor  Drive  Motor  base  is  cast  integral  with  front  pedestal.  It  is  provided 
with  an  automatic  belt  tightener  and  will  accommodate  any  standard  motor.  Motor 
should  be  7^  horse-power,  constant  speed  not  over  1200  revolutions  per  minute.  If 
motor  is  furnished  by  customer  full  specifications  are  required.  (Furnished  to  order). 

Special  Forming  Slide  For  heavy  forming  operations.  It  is  mounted  on  bed 
and  provided  with  six  power  transverse  feed  changes.  Longitudinal  adjustment  is  by 
hand  through  rack  and  pinion.  Front  and  rear  tool  posts  of  improved  type  are  provided. 
(Furnished  to  order). 

Threading  Attachment  An  attachment  extremely  simple  in  design,  attached 
to  the  machine  proper  in  a  most  convenient  manner.  It  is  equally  well  suited  and 
efficient  on  either  long  or  short,  external  or  internal  work.  Longitudinal  travel  of 
carriage  is  automatically  controlled  in  either  direction  by  means  of  conveniently  located 
adjustable  stops.  Carriage  return  is  accomplished  through  threading  attachment,  entirely 
independent  of  countershaft.  As  regularly  furnished,  it  will  cut  threads  from  I  y%  to 
20  pi.,  including  4.^2,  5^  and  n}4  pi.  Special  gears  may  be  furnished  to  order 
to  practically  meet  any  requirement. 

Threading  Tool  Holder  A  threading  tool  holder  is  made  which  permits  the 
withdrawing  and  accurate  returning  of  the  tool  to  the  previous  depth  independent  of 
the  cross  slide.  While  this  tool  is  not  necessary  for  the  satisfactory  working  of  the 
attachment  it  has  been  found  very  convenient  on  certain  classes  of  work. 

15-inch  Three-jaw  Geared  Scroll  Chuck    Is  of  an  extra  heavy  type 

and  is  regularly  furnished  with  two  sets  of  jaws  for  outside  and  inside  gripping,  and  one 
set  of  soft  blank  jaws  that  can  be  turned  to  suit  special  work.

These  machines  have  recently  been  re-designed  and,  while  retaining  the  general 
characteristics  of  the  Lincoln  Type,  differ  from  the  original  in  the  following  manner  : 
Machines  are  far  more  rigid  and  powerful  ;  Oil  Pans  surround  and  are  cast  integral 
with  the  bed  and  table  ;  Tables  are  provided  with  T-slots  ;  Spindles  are  hollow  and 
are  provided  with  draw-back  rods  ;  Adjustments,  vertical  of  spindle  and  transverse  of 
tables,  are  through  bevel  gears  actuated  by  crank  at  front  of  machine.

4  X  30-INCH    CYLINDRICAL    AUTOMATIC    SIZING 

GRINDER 

In  the  design  are  embodied  many  new  important  improvements  which  greatly 
increase  its  production  capacity  and  also  make  possible  a  greater  degree  of  accuracy. 

Automatic  Sizing  Device  A  very  simple  device,  very  easy  to  operate, 
which,  after  setting  to  the  required  diameter,  will  automatically  grind  any  number  of 
pieces  to  the  exact  size  irrespective  of  wear  of  wheel.  In  operation  it  controls  and 
utilizes  both  the  roughing  and  finishing  feeds,  thereby  obtaining  the  maximum  output. 

Back-rest  Rigid,  Automatic  Positive  Feeding  Type,  which  automatically 
follows  up  and  correctly  supports  the  work  without  yielding,  at  a  pressure  easily 
governed  to  meet  any  requirement.  In  action  it  readily  demonstrates  its  superiority 
over  either  the  yielding  or  hand  adjusted  type. 

Overhead  Driving  Mechanism     Consists  of  but  a  tight  and  loose  pulley 

countershaft.      The  other   necessary   driving    parts    have    been   simplified    and    placed 
within  easy  reach  of  the  operator  by  being  made  a  part  of  the  machine  proper.

These  machines  are  invaluable  for  work  which  can  be  reproduced  from  a 
master  form.  In  gun  and  sewing  machine  factories,  where  they  are  extensively  used, 
the  process  of  hand-fitting  has  been  practically  eliminated  upon  parts  finished  in  this 
manner.  The  machines  are  made  with  either  gear  or  belt  drive.  For  high  speed  work 
the  belt  driven  machine  is  recommended,  although  special  high  speed  gears  may  be 
furnished  to  meet  certain  requirements.

No.  2  High  Pressure  Oil  Pump 


PRATT  &  WHITN 


ROTARY   OIL  PUMP5 

These  pumps  are  of  approved  design,  made  in  the  most  substantial  manner  and  give 
excellent  results.  The  Nos.  o,  3  and  1 2  are  low  pressure  pumps  for  use  on  milling 
machines,  screw  machines,  etc. 

Special  attention  is  directed  to  the  No.  2,  perfectly  balanced,  high  pressure  pump. 
In  the  design  the  usual  stuffing  box  has  been  eliminated.  Bearings  are  hardened  and 
ground  and,  in  fact,  both  design  and  workmanship  ensure  the  highest  possible  efficiency 
in  pump  construction.  It  is  used  on  the  gun  barrel  drilling  machines  and  for  similar 
purposes  where  a  high  pressure  oil  supply  is  necessary.

*By  the  action  of  the  manufacturers  of  wrought-iron  pipe  and  boiler  tubes,  at  a  meeting  held  in  New 
York,  May  9,  1889,  a  change  in  size  of  actual  outside  diameter  of  g-inch  pipe  was  adopted,  making  the 
latter  9.625  instead  of  9.688  inches,  as  given  in  the  table  of  Briggs'  Standard  pipe  diameters.
